One of the main vulnerabilities of GNSS receivers is their exposure to intentional or
unintentional jamming signals, which could even cause service unavailability. Several …

The problem of joint Angle-of-Arrival (AoA) and calibration parameters in a wideband
scenario is addressed. The system consists of multiple sources transmitting from different …

Abstract In the Global Navigation Satellite System (GNSS), array antennas, widely used in
anti-jamming applications but seldom used in high-precision applications, can obstruct …

Array processing algorithms such as direction of arrival (DOA) estimation, deterministic
beamforming and null-steering as well as spoofer detection and mitigation are known to be …

The performance of antijamming is limited by channel mismatch in global navigation satellite
system (GNSS) antenna arrays receivers. Only when the amplitude and phase …

Resilient GNSS reception is a critical requirement for automated and autonomous driving
cars. Single-antenna receivers are prone to interference and spoofers and lack the …

Non‐stationary interferences are parts of the global navigation satellite system (GNSS)
threats; this paper focusses on the impact of intermittent interferences on the baseband …

This paper demonstrates an antenna manifold calibration method for a dual polarized
antenna array and RF front-end for use in GNSS applications. The process described in this …

The results of the interference measurement campaign carried out on board of a large
container ship over the timespan of 2.5 months are presented. The interference situation in …

Antenna calibration is a mandatory requirement to determine the attitude of a multi-antenna
receiver. Moreover, knowing the antenna attitude can vastly improve detection and …
